Enhancing Mechanical and Flame‐Retardant Properties of Huntite‐Hydromagnesite Reinforced Polypropylene Composites With Calcite, Zeolite and Intumescent Flame Retardants

open access: yesSPE Polymers, Volume 7, Issue 2, April 2026.
Thermal behavior of composites reinforced with synergistic materials. ABSTRACT As firefighting efforts increase daily, the use of fire‐resistant materials is also on the rise. However, those materials sometimes create other problems. The discovery that halogenated fire retardants are toxic is one example.

Depositional Facies, Sequence Stratigraphy, and Diagenesis of Lower Cretaceous Carbonate Reservoir, Southern Iraq: Implications for Petroleum Exploration

open access: yesJournal of Petroleum Geology, Volume 49, Issue 2, Page 312-345, April 2026.
ABSTRACT The Lower Cretaceous Yamama Formation of southern Iraq represents a key carbonate reservoir within Iraq and the Middle East, yet its complex depositional facies architecture and diagenetic alterations present challenges for predicting reservoir quality.

Long‐Term Storage of Meteoric Water in the Variscan Basement: Stable Isotope Constraints (δD–δ18O)

open access: yesTerra Nova, Volume 38, Issue 2, Page 116-123, April 2026.
ABSTRACT F‐Ba‐Pb‐Zn (±Ag) deposits near the unconformity between the Armorican and Aquitaine basins formed by mixing surface waters and brines with fluid ascending from the basement. To better constrain the source of this fluid and the conditions of mixing, we analyzed the hydrogen (δDwater) and oxygen (δ18Owater) isotopic composition of water trapped ...

Mechanochemical Enhancement of Siderite‐To‐Magnetite Conversion in Faults

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Magnetic phases in fault rocks offer potential “geothermometers” for estimating frictional heating during fault slip. However, the thermochemical kinetics of magnetic minerals subjected to shear deformation in hydrothermal fluids‐conditions typical of natural faults ‐ remains poorly understood, hindering accurate temperature estimates.

Electrical Conductivity of Amorphous and Molten CaCO3 at High Pressures and Its Implications for Mantle Conductivity Anomalies

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Impedance spectrometry experiments have been conducted on CaCO3 up to 15 GPa and 2,100 K to identify its state under high pressure. The melting temperature of CaCO3 was also determined by the falling of a Re sphere observed via X‐ray radiography. The phase transition from aragonite to the amorphous phase does not cause a leap in the Electrical
